SKF7213 CD/P4A DGG9Super-Precision Angular Contact Ball Bearing – 65 mm ID, 120 mm OD, 23 mm Width, 15° Contact Angle, Open, P4A

Product Description

What this part is:

SKF 7213 CD/P4A DGG9 single-row super-precision angular contact ball bearing. Bore: 65 mm. Outside diameter: 120 mm. Width: 23 mm. Series: 72, universally matchable spindle bearing execution. Open on both faces, cylindrical bore.

Decoding the designation:

7213: series 72, bore code 13, 65 mm bore. CD: 15° contact angle, super-precision spindle design. P4A: dimensional accuracy to P4 / ABEC 7, with running accuracy held tighter than P4. DGG9 is carried as a manufacturer part-number variant and is searchable in that form.

What these specs mean in practice:

A 15° contact angle favours speed and radial stiffness over axial capacity, which is why this execution is used on grinding and milling spindles rather than on heavy thrust duty. Basic dynamic load rating: 66.3 kN. Basic static load rating: 53 kN. Operating temperature range: -30 to +100 °C. Mass: 0.977 kg (2.15 lb).

Quantity and configuration:

One bearing, 1 Pc. Universally matchable: pieces from this execution mount together back-to-back, face-to-face or in tandem without a spacer, and a single piece also runs on its own.

Fitting notes:

Cylindrical bore, no lubrication groove in the outer ring. The bearing arrives preserved and ready to mount. Both rings locate axially against square shoulders, and the outer ring is clamped by the housing cover.

Cross-reference guidance:

7213 CD/P4ADGA, 7213 CD/P4ADGB and 7213 CD/P4ADGC are the same 65 x 120 x 23 mm bearing at extra light, light and medium universally matchable preload. 7213 ACD/P4A is a related size at a 25° contact angle. Searchable forms: 7213CDP4ADGG9, 7213 CD/P4A DGG9, 7213-CD-P4A-DGG9.
